Answer and Explanation

Determine the concentration available: 400 mg/2 mL

Simplify the concentration:

400 mg/2 mL=200 mg/mL

Volume (mL)=Required dose (mg)/Concentration (mg/mL)

Volume (mL)=160 mg/200 mg/mL

A. Temazepam 15 mg PO at bedtime PRN sleep B. Adderall XR 10 mg PO hs. C. Fluoxetine 20 mg PO every a.m. D. Guanfacine 1 mg PO daily

Correct Answer is B

Explanation

A. Temazepam 15 mg PO at bedtime PRN sleep: This prescription is clear, as it specifies the medication, dosage, route, and that it is for as-needed use at bedtime. This is an appropriate use of a sedative-hypnotic medication for sleep issues.

B. Adderall XR 10 mg PO hs: The abbreviation "hs" typically means "at bedtime," but in the context of Adderall, which is a stimulant, this usage may raise concerns about inappropriate timing. Stimulants are usually prescribed in the morning to avoid insomnia and potential side effects, so clarifying this prescription is necessary to ensure safe and effective use.

C. Fluoxetine 20 mg PO every a.m.: This prescription is clearly stated, with an appropriate dosage and frequency. Fluoxetine is commonly prescribed for depression and can be taken in the morning, making this prescription acceptable.

D. Guanfacine 1 mg PO daily: The prescription is straightforward and appropriate, as guanfacine is often used for attention deficit hyperactivity disorder (ADHD) or hypertension and can be taken daily. There are no concerns that require clarification with this prescription.
